The tool is now in position, the wing nuts beingloosened so that the frames are adjustable. The jack is now operated andthe plunger I3 pressing against the head block 4 will force the lowerframe 8, 9, l against the upper end of the sleeve, driving the same intothe cylinder. The pressure applied to the top of the sleeve is exertedbetween the two resistance points, one above and one below the pressurepoint and both falling within the plane of the sleeve or cylinder and inthis there is no lateral pressure or pull upon the cylinder block andbreakage of the same is positively prevented. In this instance the lowerframe is movable with respect to the cylinder block while the upperframe is stationary. In the event it is desired to replace the jack inuse by another while the operation is in progress, the frames may betemporarily locked in adjusted position by tightening the wing nuts.when it is desired to remove a sleeve or bushing from the cylinder blockthe pull rod I4 is provided with an annular pulling disc I! and nut IS.

The disc I! is formed with a slightly reduced portion it, said discbeing of a diameter slightly less than the interior bore of the cylinderso that it is movable therethrough, but of a diameter greater than thebore of the sleeve or bushing i 9 to be removed so that it will not passtherethrough. A cylindrical pedestal 20 of slightly greater diameterthan the cylinder bore so that it may be disposed about the mouth of thebore, and of greater length than the sleeve to be removed, is employed.With this pedestal in place upon the cylinder block the tool is placedthereupon, the end plate 9 resting upon the pedestal and the pull rodextending centrally therethrough and through the cylinder and the sleevetherein to be removed. The pulling disc is now applied to the rod, as isalso the nut l6, from underneath the cylinder. By operating the jacktheupper frame is raised, as denoted in dotted lines in Fig. 2, the discl1 withdrawing the sleeve from the cylinder and moving it into thepedestal, the lower frame being stationary during this operation. Thesleeve being removed rests, during this operation, upon the shoulderformed by the Junction of the reduced portion' I I of the pulling discand the main body portion of the same.

What is claimed is:--

1. In cylinder sleeve presses, a movable frame, a stationary frameconnected thereto, a pedestal receiving said stationary frame, aconnection between said movable frame and the sleeve to be extracted,and actuating means for said movable through said pedestal and thesleeve to be extracted, and a pulling disc at one end of said pull rodengaging one end of the sleeve.

4. In cylinder-sleeve presses, an outer frame,

an inner frame connected thereto, a pedestal receiving said inner frame,a connection between said outer frame and the sleeve to be extracted,and actuating means for said outer frame disposed within the confinesthereof upon the upper end of said inner frame.

5. In cylinder sleeve presses, a pair of adjustable frames connectedtogether, one of said frames including a base end plate for applicationto the sleeve under operation, both of said frames being wholly disposedthereby in spaced relation to the upper end of the cylinder, and a pullrod carried by one frame for connection to i the lower end of thecylinder as the sleeve is being inserted.

6. In cylinder sleeve presses, a pair of adjustable frames connectedtogether, one of said frames including a base end plate for directapplication to the sleeve under operation, both of said frames beingdisposed above and in spaced relation to the upper end of the cylinderthereby, a pull rod carried by one frame and extending through thesleeve and cylinder, an anchor disc carried by said pull rod, and a nutcarried by said pull rod. a
